Thanks Adrian for your valuable comments. My comments below.

The former. Sorry if it was not fully explicit, this was the intent of this sentence in the description: "can be exposed to the application to make efficient service placement and selection decisions". From this description, the focus is on exposure to the application, which btw could be both the service provider (for placement decisions) or the application running on the host or as a proxy (for selection decisions). So this would not overlap with CATS, but rather complement CATS (similarly to the presentation we will have in the CATS session, to your point).

It's difficult to assess the potential audience. We opted for keeping it conservative/humble on the expectations as a starting point, while freeing up the larger room for other side meetings since the resource appeared scarce. We apologize if this appears to be under-dimensioned with our forwarding of this invite to five WGs. These five groups were collectively selected by the organizers, and we understand there is a fine balance of expectations. Certainly we can learn and improve in the future, so thanks again for your feedback, and sorry in advance for any potential imbalances.

Jordi

Hi Jordi,



Thanks for the heads-up on this meeting. It will clearly be of interest to the CATS working group although it is unclear from your brief summary of the issue whether you intend exposure of information to “the application” (by which I think you may mean the programs running on a host) or “the network edge” (which is clearly the scope of CATS).



I know you will have time on the CATS agenda (on Friday) to present your draft, https://datatracker.ietf.org/doc/draft-rcr-opsawg-operational-compute-metrics/. But, as CATS is not happening until after your side-meeting, it might help to try to resolve the main question of why your topic is not fully in scope for discussion in CATS.



By the way, I notice you have picked the side-meeting room that has a maximum capacity of 14 people. Since you sent your notification to five working groups, and since the topic was of sufficient interest to cause the formation of the CATS working group, I wonder whether you may have under-estimated the potential attendance.



Cheers,

Adrian

Subject: [bmwg] IETF ALTO 118 side meeting on exposure of network and compute information for edge computing



Hi CATS/OPSAWG/ALTO/IPPM/BMWG WG mailing list members:



We are going to have a side meeting to discuss "exposure of network and compute information for edge computing applications":

  *   Side meeting wiki: https://wiki.ietf.org/en/meeting/118/sidemeetings#Wednesday
  *   Topic: Edge computing
  *   When: Wed Nov 8, 15:30 -17:00,
  *   Where: Karlin 4



As the industry has reached peak computational centralization, compute needs communication to scale through distributed computing. There is a need to have a forum to discuss how the two sides of the same coin (compute and communication) can be exposed to the application to make efficient service placement and selection decisions. This is especially important at the edge of the network, where services such as distributed AI, XR/VR, vehicle networks (V2X), etc. need this compute and communication information to be efficiently deployed and managed. Exposed information should also account for the application footprint reaching out to cellular networks and for trust capabilities exposure.



The session will include talks on the following topics. If you are interested in presenting an additional related topic, please reach out to us by replying to this e-mail no later than Sunday Nov 5th.



Side meeting presentations/topics:

  *   Compute information exposure for service placement and selection.
  *   Cellular information exposure to Internet applications.
  *   Security information exposure for trust modeling and measurement.
  *   Southbound mechanisms to obtain network and compute information.
  *   Summary of conversations: key points and discussion of next steps.



Thanks,

Jordi

On behalf of this side meeting's organizers
